In addition to Westlaw and Lexis, there is an enormous amount of legal research that can be done through the internet.
Virtually every state and federal court procedural and evidentiary rule is available, as are federal and state regulations from securities to land use; almost every state and federal court opinion is available without accessing West or Lex; briefs and pleadings in state and federal appellate courts can be accessed; every arbitration body posts its rules and decisions on the internet (AAA, NASD, NYSE, etc); law reviews from practically every law school in the nation are accessible, as are state and national bar journals; legislative debates, commentaries, and proposals are accessible; etc. etc.
Rep. Delay's shock at a Justice doing his own research on the internet is just bizarre. Is he also shocked that most of the Justices on the Supreme Court also do their own drafting?
But, one might ask how reliable these sites are. They know the tons of law books on their shelves can be counted on to have been proofread with a fine tooth comb -- the publisher's reputation rests on it. Nobody's attesting to the accuracy of what you can Google up.
I have no idea what he's even trying to say, unless it's a cynical play to the clueless peanut gallery crowd who think that "The Internet" is all about porn and bootlegging.
It's as if you accused Justice Kennedy of "doing his research by reading" to an audience that doesn't understand the difference between Blackstone and the authors of the Weekly World News.
